Moss surprised many in Pelican Rapids by appearing at the graduation ceremony.
Moss’ reason for being there was to hand a high school diploma to senior Kassi Spier, said Pelican Rapids Public School District Superintendent Deb Wanek.
Spier developed a friendship with Moss during his playing days with the Minnesota Vikings.
Wanek said Spier battled leukemia in her youth. Then, in 2004, Spier’s father died in a car accident. And in 2013, Spier was diagnosed with a brain tumor.
